Scorpio energy is inherently negitively charged at a base level. However Scorpio is different because it has a inborn method to change energy from a negitive to a positive. That being said the Scorpios that this User is experiencing are all at a lower level in the evelutionary stages, this probably stems from something in the users chart, not just from external forces. Otherwise they would experience all evolutionary stages of Scorpios, not just the lowest stage.
Scorpio energy works differently too, from even let's say Capricorn energy, as it's less direct and seeps through the natives energy. (Think Capricorn drys the pond whislt Scorpio makes it toxic)
I agree that it will be part of his energy he needs to work out for himself and it is his responsibility but that does not mean he has not been played with.
